变更

workflow_dispatch 增 model 入参(默认仍 org var MODEL1)。背景:MODEL1=kimi-for-coding 经 api.kimi.com 返回 200+异常体(计量自检 rc=3,两次复现 run 32793862619/32794290751);同端点 glm-4.5-air 实测健康(llm-connectivity run 32794695925,metering exit=ok)。本旋钮不改变计量语义(wrapper 契约不变)。

待 owner

org var MODEL1 是否常切 glm-4.5-air(PAT 无 org 变量写权,未代改)——建议醒后定夺;MODEL1 修复前 adversary 调度一律带 -f model=glm-4.5-air。

Summary by CodeRabbit

  • 新功能
    • 手动运行攻击流程时,新增可选的模型参数。
    • 未指定模型时,自动使用默认模型配置;指定后可临时覆盖默认设置。

PR Summary by Qodo

Add model override input to adversary GitHub workflow (emergency knob)

✨ Enhancement ⚙️ Configuration changes 🕐 Less than 10 minutes

Grey Divider

AI Description

• Add a workflow_dispatch input to override the adversary “judgement” model at run time.
• Default behavior remains unchanged by falling back to org var MODEL1 when input is empty.
• Enables fast mitigation for vendor model rename/offline without changing metering-wrapper
 semantics.

High-Level Assessment

The following are alternative approaches to this PR:

1. Make input a choice/allowlist
  • ➕ Prevents typos and invalid model names
  • ➕ Documents supported models in the UI
  • ➖ Requires maintenance when vendor models change
  • ➖ Less flexible for emergency hot swaps to new names
2. Switch default by editing org var MODEL1 only
  • ➕ No workflow changes needed once permissions/process exist
  • ➕ Centralized control for all runs
  • ➖ May be blocked by permission constraints (no org var write access)
  • ➖ Slower response during incidents; requires org-level action

Recommendation: Current approach (optional input override with fallback to vars.MODEL1) is the best incident-response knob: it is minimal, preserves existing wrapper/metering semantics, and avoids requiring org-level variable changes during outages. If this becomes long-lived, consider evolving the input into a choice/allowlist to reduce operator error.

Merge Risk: 🟡 Moderate · up to e95d9

The new model override input currently does not affect the adversary execution, so dispatching with a different model can still use the configured default. This is a concrete correctness issue in the requested behavior and should be fixed before merging.

Informational

1. Model override ineffective 🐞 Bug ≡ Correctness
Description
LLM_MODEL is updated at job-level to use inputs.model, but the actual “攻击” step still sets
LLM_MODEL to vars.MODEL1, and the adversary runner passes --model from the locked YAML config,
so workflow_dispatch model will not change the model used for the metering-wrapped call.
Code

.github/workflows/adversary.yml[65]

+      LLM_MODEL: ${{ inputs.model || vars.MODEL1 }}
Relevance

● Weak

Recent precedent rejected an analogous unused workflow model input because execution remained
hard-coded; this finding matches that pattern.

PR-#64

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The PR changes job-level LLM_MODEL to use inputs.model, but the attack step still overrides
LLM_MODEL to vars.MODEL1. Separately, the adversary wrapper call uses --model from the locked
config (ADVMODEL), which is currently hard-coded to kimi-for-coding, so changing LLM_MODEL in
the workflow cannot affect the model used by the metering wrapper.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The new workflow_dispatch input `model` is not actually used by the adversary call path.

Even though job env sets `LLM_MODEL: ${{ inputs.model || vars.MODEL1 }}`, the “攻击” step overrides `LLM_MODEL` back to `vars.MODEL1`, and `pipeline/adversary/run-adversary.sh` invokes the metering wrapper with `--model` taken from the locked config output (not from `LLM_MODEL`).

### Issue Context
- The PR intends an emergency knob to override the judge model.
- Current adversary implementation selects model via `adversary-config.yaml` / `models.yaml` lock and passes it explicitly as `--model`.

### Fix Focus Areas
- .github/workflows/adversary.yml[170-176]
- pipeline/adversary/run-adversary.sh[48-92]
- pipeline/adversary/adversary-config.yaml[9-23]

修正模型覆盖链路。

inputs.model 当前无法影响攻击调用。Line 174 的 step 级 LLM_MODEL 会覆盖 Line 65 的 job 级值。run-adversary.sh 也不读取 LLM_MODEL,而是从 adversary-config.yaml 获取 kimi-for-coding,再传给 wrapper 的 --model。请将覆盖值显式传入 run-adversary.sh,并在 wrapper 调用及配置锁定报告中使用和记录该值。
